基于SLP的地铁施工场地安全布局优化方案

SLP-based optimization of subway construction site safety layout

为提高地铁施工现场的安全管理水平,以福州市某一地铁施工现场为例,采用系统布置设计(SLP)方法优化地铁施工场地布局;根据功能分区,将地铁施工场地划分为施工区、机械设备停放区和钢支撑堆放区等共10个单元;分别分析这10个单元之间的物流和非物流关系,并基于分析结果绘制作业位置相关图,按物流与非物流关系1∶1加权,得出作业单元综合关系图,进而提出2个初步优化方案;采用加权因素法评价上述2个方案,得出地铁施工场地布局的最优方案。结果表明:运用系统布置方法优化得出地铁施工场地布局方案,有助于提高施工效率,加强施工现场安全管理水平。

To improve the safety management level of the subway construction site,a certain subway construction site was taken as an example,and SLP method was used to optimize the layout of the subway construction site.According to the functional division,the subway construction site was divided into 10 operating units such as a construction area,a mechanical equipment parking area,and a steel support stacking area.The logistics and non-logistics relationships between the 10 operating units were analyzed separately.A job position correlation map was drawn based on the analysis results.The operating units were integrated according to the 1∶1 weighting of logistics and non-logistics relationships.A diagram was obtained for comprehensive relationships between the operating units.Then two preliminary optimization schemes were put forward.Using the weighted factor method to evaluate the above two schemes,the optimal scheme of the layout of the subway construction site was obtained.The results show that the layout scheme of the subway construction site obtained by using the system layout method can improve the construction efficiency and the safety management level of the construction site.
